To all whom it may concern:

Be it known that l, GUSTAV B. Kano, a citizen of the United States, anda resident of Chicago, in the county of Cook and State a of lllinois,have invented certain new and useful Improvements in Gearing forPortable Power-Tables; and I do hereby declare that the folowing is afull, clear, and exact description thereof, reference being had-to andto the letters of reference marks. thereon, which form a part of thisspecification This invention relates to gearing for power tables moreparticularly intended for use in kitchens of houseolds and the like andconsists of the matters hereinafter described and more particularlypointed out in the appended claims.

Fig. 10 is a view representing a verticalsection through Fig. 9 in a plane indicated by the line Ill-10 thereof.Fig. 11 is a view representing on an enlarged scale a partial section ina plane indicated by the line 11-11 of Fig. 3. Pi 12 is viewrepresenting a partial'vertica section through Fig. 3 in a planeindicated by the line 12-42 thereof.

Referring now to that embodiment of my invention illustrated in thedrawings, 10

indicates a table having four upright legs 11 and top 12. Said table maybe of any convenient construction and is preferably made of wood and thetop provided with a sheet metal covering 13. The top'lB hasv anelongated slot, symmetrically located with reference to its sides andends, to receive a plate 1% which has a marginal horizontal flange 15-let into the table top and a vertical flange 16 which engages againstthe vertical sides of the slot. 19 indicates an upright tubular brackethaving a flat annular base 20 which is bolted to the plate 14. Saidbracket has an annular apertured boss or extension 18 below said baseengaging within an aperture in the plate 1 said aperture beingsurrounded by a flange 17 that embraces said boss. A vertical operat inSaid bracket is enlarged at its upper end to form gear casings 2t, 25,the one above the other, which inclose gears on the vertical operatingshaft 21 and on two horizontal auxiliary shafts 27, 29. the bracket isbored centrally to provide bearings for the vertical operating shaft 21which projects downwardly through the boss 18.

The lateral walls of the gear casings 2t, 25 are extended on one side ofthe bracket to form long bearings 27, 29", for the re spectivehorizontal shafts 27 and 29. 22,

indicate vertically spaced beveled gears fixed.

shaft 21 has hearing in said bracketing with beveled gears 30, 31 fixedto the horizontal shafts 27, 29. The upper gear casing 25 has aremovable cap'32 and the lower gear casing a removable side plate 33,for the purpose of assembly and renewal or removal of the gears.

Each of the shafts 29, 27 has an enlarged end part 32" forming a radialshoulder which, together with the gear fixed to said shaft in theassociated casing, acts to hold the shaft against longitudinal movement.Each enlarged part 32 of said shafts has a projecting and rib 33 forengagement in a socket or other suitable coupling device for connectinsit to the driven shaft at a rotary operated hitchen utensil or othershaft that may be supported above the table, as will he presentlydescribed. 1 34 indicates a shelf secured to the table said motor is ofthe electric type, a suitable switch 36 being secured to the table belowthe top for turning on the electric power when the motor is to bestarted. lhe electric connections to the motor are not shown and may beof any usual or familiar kind.

37 indicates the motor shaft which has its axis located in a horizontalplane. Said motor shaft is-operatively connected to drive the verticaloperating shaft 21 which depends below the table top 12, as heretoforedescribed.

A motor of comparatively low horse power may be used in connection withmy improved power table, and inorder to use a high speed on said motorand at the same time drive the operating shaft 21 at the low speedrequired, a'speed reducing mechanism is provided in the connectionbetween the motor; shaft 37 and the vertical operating shaft 21.

38 indicates a casing supported on the shelf 34 adjacent to the motor.39 indicates a horizontal shaft havingbearing in said casing andprovided with a worm 40. The shaft 39 is arranged with its axis in linewith the axis of the motorshaft 37 and has fixed toits end adjacent tothe motor shaft a dish 41. similar disk 42 is fixed to the abutting endofthe motor shaft37 and a dish 43 engaged between the disks 41 and 42 isnon-rotatively connected to each bolt 43 which fits into recesses ineach face of the disk 43. Saiddisk 43 is made ofmaterial such as leatheror the like, capable of providing a slight play between the disks 41 and42, so that a slight yielding between the disks 41 and 42 is provided toprevent jarring when the motor is first started. One of the disks 41,42, as shown in the drawings thedisk 42 upon the motor shaft, isprovided with a groove 42 in its periphery for the application of a beltwhen, for-example, it is desired to use the motor to drive somemechanism not connected with the table, as a washing machine, or thelike. p

In thecasing 38 adjacent the shaft 39 is 'rotatably mounted a verticalshaft 45 which has fixed to it a worm-gear 45 in mesh with the worm 40.The shaft 45 is preferably provided with antifriction bearings, as shownin the drawings (see Fi 5). Said shaft projects above the top 0 thecasing and has pinned or otherwise rigidly attached to it. a couplingmember 46 provided with a conical recess 47 in its upper end. The shaft45 is arranged substantially in vertical alinement below the operatingshaft 21 which terminates at a point spaced above it and b said shaft 21has fixed to it a socket member 48 having a conical recess 49 at itslower end. .A short shaft 50 connects the two socket members 47, 48,said shaft being provided with pins at its ends which engage mensesvertical slots formed in the recessed socket members. lt-is apparentthat this construction permits a slight play in the shaft 50 thatconnects the shaft 45 with the operatmg shaft 21. This makes exactalinement between 1 the shafts 45 and 21 unnecessary. This constructionsaves time and labor in assembling the device and also prevents bindingof the operatingparts in case the motor, worm-gear or casing areslightly displaced with reference to the operating shaft either whenshipping the table or by shocks or jars that it may be subjected to whenin use.

From this description it is apparent that the rotary movement of themotor-shaft 37 will communicate a rotary movement to the verticaloperating shaft 21 and through it to the horizontal auxiliary shafts 27and 29, at a speed reduced below that of the motor-shaft, so that amotor of high speed but low power may be used to communicate a slowspeed of higher power to said auxiliary shafts.

The plate 14 is provided with a longitudinally extending channel'51, thecentral axis of the same being located. in the vertical plane of thehorizontal auxiliary shafts 27, 29. The channel is wider at the bottomthan at the'top, having outwardly inclined side walls 52. I) Saidchannel is adapted to receive a base 53 having inclined lateral edges'54and constituting a support for the shaft to be driven, or in the caseof a kitchen utenthe said lever. consists of a short arm 57 I which isfulcrumed in a recess in the plate 14 adjacent the channel 51 and of along arm 58 (see Figs. 6 and 7) which is offset from the first named armso as to be capable pf a swinging movement in a plane below the tabletop. Said long arm 58 extends through a slot 59 (see Fig. 1) in theframe work of the table.- ltis apparent from this description that byswinging the lever 55 in one direction the cam end 56 thereof may bebrought into forcible engagement with one of the lateral edges 54 of thebase 53 so as to force its other inclined edge 54 into close engagementwith the opposite overhanging flange or side wall of the channel 52 andthus rigidly lock the base in the posi tionin which it is placed in saidchannel.

As shown in the drawings, the base 53 has fixed to it an uprightstandard 60 provided at its upper end with a journal bearmg 61 for ahorizontal shaft 62. Said bearing is located at such a level above thebase 53 that when said base is in lace the central axis of the bearingwill in alinement with the central axis of the lower horizontal shaft27. The shaft 62 is provided with an annular groove 63 within the'journal bearing 61 and the hearing has a vertical aperture 64:extending tangentially to said- 68 at each end provided in the bottom ofthe recesses with diametric grooves 69. The shaft 62 has a diametric rib62 at its inner end similar to the rib 33 on the horizontal shaft 27,aid ribs being adapted to engage in the grooves 69 of the oppositelylocated recesses 68, when the shaft 62 is locked in the journal bearing61, as above described. As shown the shaft 62 has "fixed to its outer'end a pulley 70 for driving connection with a pulley 71 adapted foroperating an icecream freezer 72 supported in a swinging bracket 73attached to the shelf 34;. Said ice cream freezer is removable from thebracket 73 which may be swung in a familiar manner up into the positionindicated by dotted lines in Fig. 1 when the ice cream freezer is not inuse and the shaft 62 is wanted for driving) other mechanism. An otherdevice may e operated by the shaft 62 or said shaft may e provided withan emery-Wheel or any other tool that it ma be desired to use. insteadof the standard 60 and the shaft 62 any rotary driven kitchen utensilhaving a base 53 like the standard 60 may be used on my power table, asin the ease of the power table described in the intent to Goehst andCarpenter, No. .,G:12,666, issued July 16th, 1912, the shaft of saidrotary driven utensil heing coupled to one or the other of the auxiliaryshafts to swing in the 27, 29, depending upon its height above thetable, inthe same manner as the shaft 62 as herein described.

I claim as my invention 1. In combination with a power table, a verticalshaft extending above and below said table, a horizontal driven shaftsupported below said table, a casing in which said horimntal shaft hasbearing, a worm within said casing fixed to said shaft, a vertical shafthaving bearing in said casing and located substantially in verticalalinement below said first named vertical shaft, a worm gear fixed tosaid second named vertical shaft and in mesh with said worm, the adjacent ends of said vertical shafts being spaced apart, a connectingshaft extending between the adjacent'ends of said two vertical shafts,and coupling means connecting the ends of said intermediate shafts witheach of said vertical shafts, said coupling means permitting angularshifting movement between said intermediate shaft and said two uprightshafts.

.2.v In combination with a power table, a rotative driven shafthorizontally supported above said table, a driving shaft, means operativel connecting said driven shaft and said driving shaft, a standardfor supportin said driven shaft, said standard having a ase, a plateattached to the table below said driven shaft and extending in a planeparallel to said driven shaft, said plate having an elongated channelprovided with inclined overhanging side walls and said base havinglateral outwardly inclined edges, said base being narrower than saidchannel, and means for locking. said base to said channel comprising alever fulcrumed plane of said channel and having a cam en adapted forengagement with one lateral edge of said base.
